Recent nuclear projects in Europe and the US have taken far longer to complete than new builds elsewhere. Here’s how to speed up the process. Construction duration and cost overruns have troubled the Western nuclear power industry for years, with time to completion as much as twice as long as those in China and South Korea, for example. Problems include poor project management, complex and immature designs, weak supply chains, and little collaboration among stakeholders. By promoting design simplicity, supporting suppliers, fostering collaboration, and improving project management, the industry can significantly improve its construction efficiency and help boost the share of power from this key low-carbon source.
